The specific embodiment

As Figure 1-3, a kind of manufacturing method for glass fiber reinforced plastic pressing mould, this mould adopt steel as the framework fixed mould by unsaturated polyester resin and the glass fibre main material as mould, and its preparation method is:

1, make wooden model or gypsum mold (former or formpiston) according to the designing requirement of product, and evenly stamp demoulding wax.

2, manual brushing adhesive clothing layer on the mould product after waxing, the thickness of gel coating resin is generally 0.3-0.4mm.

Gel coating resin needs brushing at twice, and brushing thickness at 0.4-0.6mm, after ground floor solidifies, then is brushed for the second time for the first time, and brushing for the second time is mainly that benefit is even, makes gel coating resin thickness more even, and thickness is at 0.5-0.8mm.Then carry out polishing and polishing, make its thickness at 0.3-0.4mm.Gel coating resin mainly plays and beautifies and the anti-aging effect.Its thickness must be controlled at 0.3-0.4mm, and too thin not having beautified and the anti-aging effect, and too thick meeting reduces its toughness, can cause it to break when stressed.

(gel coating resin is the S-598 resin compound, and its composition is: every kilogram of S-598 resin, curing agent

(peroxidating ethanol) 8-12ml, promoter (T-8A) 8-12ml).

3, after the gel coating resin sanding and polishing, manually paste 3 layers of alkali-free surfaces felt (specification is 30g/ ㎡), the size of employing is the S-904 resin compound (composition of mixture: every kilogram of S-904 resin, curing agent

(peroxidating ethanol) 22-27ml, promoter (T-8A) 22-27ml require to paste closely, evenly.

The S-904 resin has high mechanical property, high chemical resistance, and high heat distortion temperature is used this resin compound and can be improved the overall performance of mould as bonding agent, strengthens its resistance to chemical attack, at high temperature keeps mould and die accuracy.

4, paste 3 layers of alkali-free glass fibre (chopped strand), size adopts S-904 resin blend thing equally, when pasting every one deck alkali-free glass fibre, must wait for 20-30 minute, avoids producing high temperature.

5, until above alkali-free glass fibre and the S-904 resin bed cooling after, more manually paste 3 layers of medium-alkali glass fibre woven roving, size is all S-904 resin blend thing, but need add the iron powder of 10-20g in every 1kg size.

6, after 20-30 minute cool time, then paste 3 layers of medium-alkali glass fibre woven roving, the same previous step of size.

7, by the previous step method, then paste 4 layers of medium-alkali glass fibre woven roving.

8, by the previous step method, paste again 4 layers of medium-alkali glass fibre woven roving, but size changes S-685 resin blend thing into, the composition of mixture: every kilogram of S-685 resin, curing agent (peroxidating ethanol) 18-22ml, promoter (T-8A) 18-22ml, iron powder 10-20g.The S-685 resin has high heat distortion temperature, and is ageing-resistant, and excellent bending property and high rigidity are used this resin as bonding agent, can allow mould keep high intensity, and the ageing-resistant ability of mould is strengthened.

9, by the previous step method, then paste 4 layers of medium-alkali glass fibre woven roving.

10, by the previous step method, then paste 4 layers of medium-alkali glass fibre woven roving.

11, by the previous step method, then paste 4 layers of medium-alkali glass fibre woven roving.

12, by the previous step method, then paste 5 layers of medium-alkali glass fibre woven roving.

13, by the previous step method, then paste 5 layers of medium-alkali glass fibre woven roving.

14, by the previous step method, then paste 5 layers of medium-alkali glass fibre woven roving, but size changes into

S-191 resin blend thing, the composition of mixture: every kilogram of S-191 resin, curing agent (peroxidating ethanol) 10-15ml, promoter (T-8A) 8-10ml, iron powder 10-20g.The S-191 resin also has high mechanical property, and shrinkage is little, the intensity advantages of higher.

15, by the previous step method, then paste 5 layers of medium-alkali glass fibre woven roving, so far fiber reinforced plastic mold is completed.

16, according to mould needs welding-on mould fixed frame, at the vertical band steel 2 of the interior installation of mould housing 1 and horizontal band steel 3, mould stiffener 9, longitudinal mold inner support 10, transverse mold inner support 11 are arranged on mould housing 1., be fixed on mold frame the previous glass fiber reinforced plastic pressing mould of making and fully solidifying with dormant bolt 12.The effect of band steel is be convenient to fiber reinforced plastic mold and mold frame fixing, and the effect of support is the structural strength of strengthening unitary mould.
